Review on 3Pcs 500Ml CVNDKN Wash Bottles W/ Scale -16 Oz: Plastic Safety Lab Squeeze Bottle by Randolph Iglesias

I bought these for washing window frames, one with soapy water, one to rinse. They worked fine but after a short break for coffee, they did not work the same. The one with soapy water had split the tube so air got in and made it unusable. I don't give up so easy though, I cut off a length of surgical tubing and it fit over their tube so I could keep using it. The plain water one had a split tube the next morning when I had planned to finish another set of windows. The same fix made it usable but I have to ask - why would they use tubes that are self splitting?They were very affordable and like anything, a lower than expected price is a tip-off.
